965-1176-003, MK-VI, EGPWS
- Class A certified TAWS
- Enhanced Ground Proximity Warning System (EGPWS)
- Is a rack mount GPWS and terrain awareness/warning computer
- Terrain Awareness System (TAWS) that performs the functions of a standard Ground Proximity Warning System (GPWS) as well as performing the enhanced functions of terrain display & warning
- Exceeds FAA TSO-C151b Class AÂ requirements
- Optimized for turboprop aircraft and provides protection against controlled flight into terrain (CFIT)
- Uses aircraft inputs such as position, attitude, air speed and glideslope, which along with internal terrain, obstacles and airport databases predict a potential conflict between the aircraft’s flight path and terrain or obstacle
- CFIT warnings include: Rate of descent, terrain closure rate, excessive altitude loss after descent, terrain closure rate, excessive altitude loss after takeoff or missed approach procedures, insufficient terrain clearance, descent below glideslope, and excessive bank angle
- Callouts at various radio altitudes & DH minimums during approach
- Provides audio caution or warning alerts (visual alerts when coupled w/display)
- When coupled with a display, the surrounding terrain can be viewed relative to the aircraft’s position, providing strategic terrain information up to 30 mins before a potential terrain conflict
- Basic ground proximity warning modes 1-5
- Mode 6 altitude callouts and bank angle alert
- Terrain clearance floor
- Terrain and Obstacle Awareness alert and display
- Terrain map w/runways >= 2000′ in length
- Internal GPS card
- Front loading updateable database
- External Configuration Module
- Internal heated blanket for operation outside of the heated area of the aircaft
- Fixed Gear operation
- Type of supported displays is limited and does not typically include EFIS display
- Terrain database included with the computer is regional having three separtely defined databases for the Americas, Atlantic, and Pacific
- MK VI computer uses a Configuration Module, GPS Antenna, OAT Sensor, and Smart Cable (PCMCIA interface)
